Arguments

Description

kOfxActionBeginInstanceChanged and kOfxActionEndInstanceChanged are used to bracket all kOfxActionInstanceChanged actions, whether a single change or multiple changes. Some changes to a plugin instance can be grouped logically (eg: a 'reset all' button resetting all the instance's parameters), the begin/end instance changed actions allow a plugin to respond appropriately to a large set of changes. For example, a plugin that maintains a complex internal state can delay any changes to that state until all parameter changes have completed.
